call me the bad guy here but I wanna trade in my 09 with lifter tick and get an 11 with way less miles, a bigger cab, and in better shape. so I don't think there was lifter tick when I got the truck with 102,000 miles, but after I got my first oil change (syn) I noticed it.. and it just seems worse and worse with each oil change. if I remember correctly sea foam silenced them for a bit. looking for some tips to hide lifter noise when I go to trade in... I know im the bad guy but im probably going to already take a hit on the trade in and im pretty sure the dealer I got it from put super thick or thin oil (whichever hides lifter tick) with some sea foam and had me test drive it, maybe im crazy, maybe the next truck will end up like this one... test drove it today with 65k miles on it, good condition 2011 sierra. wondering if it is okay, how can I prevent the lifters from going bad? range delete system? thanks a ton

On high mileage engines, lifter ticks are USUALLY caused by blocked oil ports.

 

Drain 1 qt of oil from your crankcase, and replace it with 1 qt of non synthetic transmission fluid. Drive the vehicle @ low rpm's for about 15 min.

 

Drain all the oil and replace the filter, the transmission fluid SHOULD have unclogged the orifice in the lifter (IF that is the problem).

 

The only other cause of a lifter tick is if it is bent, and in that case it must be replaced.

Just drive it, you'll be fine. Mine is getting close to 300,000, and has had the lifter tick since day one. Still all original.

even if it is fine as sahls01gmc says, I still want a black crew cab with less miles, and I think (could VERY well be wrong) that lifter issues cause more damage in the gmt900 trucks with AFM than with older gens. on top of that I want something that needs less body work. thanks Gurrzt ill be sure to try that tonight. hoping to make the deal happen on Saturday but we will see

Hey, can't blame you for wanting/needing a bigger cab. I'm in the same boat, just waiting til this thing says she's done working......

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
